In addition, the City of Mission and Sharyland WSC have additional rights thatUnited pumps for them. Table 1 provides a tabulation of the diversion by UIDover the past 31 years. Also included in the table is the overall deliveryefficiency that has improved substantially overtime.
In recent years, UID has delivered more municipal water but has also becomemore efficient through completion of various water conservation projects fundedby the Bureau of Reclamation. The current delivery efficiency of the District isabout 85%.
UID also manages Hidalgo County Irrigation District No. 16 (D16) that divertswater upstream of the UID First Lift Pump Station. D16 serves about 12,000acres of irrigated farmland and is authorized to divert up to 31,624 acre feetunder Certificate of Adjudication Number 802-000.
3. Conservation
The UID boundary is shown in Figure 1 along with Water Certificates ofConvenience and Necessity (CCN) Boundaries of its PWS customers. Figure 2displays UID's First Lift Pump Station along the Rio Grande and the ProposedStorage Facility site. Other than the canal between the First Lift and theSecond Lift Pump Stations, UID has no other off-channel storage. The storagecapacity of this section of canal is about 80 acre feet. UID orders water fromthe Rio Grande Watermaster at least 48 hours prior to the time it plans to divertthe water from the Rio Grande. The Watermaster releases the water from
Falcon Lake according to the order schedule and 48 hours represents the timeneeded to execute the order and the time for the water to travel from Falcon to
the UID First Lift Pump Station. Once an order is released from Falcon itcannot be stopped, so the diverter must divert the water on time or it is lostdownriver to the Gulf of Mexico. TCEQ Chapter 303, Operation of the Rio
Grande, dictates the procedures for ordering and diverting water and theWatermaster accounting methods. The Watermaster charges the Diverter'swater right account the higher of the actual amount ofwater diverted or 90% ofthe order. UID typically orders water one week in advance and may amend theorder two days in advance as required. During times of unpredicted wetweather, predicted irrigation and municipal demand can be significantlyreduced resulting in UID's inability to divert ordered water. The Watermasterwill charge 90% of the original order.

The difference between the Watermaster charge and the order are "River
Losses" and represent an estimate of the amount of water charged to theDiverter's account that actually flows downstream to the Gulf of Mexico. The
purpose of this storage facility is to provide a place to store water that has beenordered and will be charged to UID's account.
Table 2 provides the amount of water UID lost downriver for the five calendaryears from 2008-2012. The Table is based upon UID's records of the amountof water ordered each week and the amount of water diverted. The difference
between 90% of the order and the actual amount pumped, if positive, is the
river loss. In general, over the five year period, UID has lost approximately1,500 acre feet per year, or 3.7% of the amount diverted, downriver to the Gulfof Mexico.
There are times when No Charge Water is available in the Rio Grande, andUID can utilize the reservoir to store No Charge water when it is available.
There is less opportunity for No Charge water above the Anzalduas Dam wherethe UID First Lift is located because the Watermaster is able to make
adjustments at Anzalduas. In addition, there are times when UID may not beable to divert ordered water because of power or equipment failures at the
river. Assuming these two events offset each other, UID will conserveapproximately 1,500 acre feet per year by construction of the storage facility.The storage facility will be located on UID's Main Canal between the First andSecond Lift Pumping Facilities. Water stored in the facility will be divertedunder UID's Certificate Adjudication No. A847-001. The Diversion point andthe place of use will not change.
4. Hidalgo County Irrigation District No. 16
UID manages Hidalgo County Irrigation District No. 16 (D16). D16 is locatedon the Rio Grande about 14 river miles upstream of the UID facility. During
times when D16 cannot divert ordered water due to wet weather, water ordered
by both Districts can be amended such that UID can divert DIS's water andstore it in the proposed facility. Table 3 outlines D16's river losses based onwater ordered and water pumped for the period from 2008-2012. Typically,D16 loses about 1,000 acre feet per year.

This strategywas submitted by United Irrigation District to the RWPG.
Description
This strategy is for anoff-channel storage reservoir between thediversion point from the RioGrande and the first pumping station inthe United Irrigation District system.There isa delaybetweenthe time that the users in the district request water and the time when the IrrigationDistricts can divert that water from the river because of the distance that the water must travel.Water isordered 2-8 days inadvance based on forecasted needs. In the time (generally 2-3 days)between when water is released and when it is diverted, rainfall in the district can fill theavailable storage space in the main canals and reduce demands. When this happens, the Districthas nowhere to store the water they have requested buttheirwater right holder account ischarged with 90% of thevolume that was released for them. United ID has quantified theselosses annually from 2008 to 2012, estimating anaverage of 3.7% of their annual diversions islost as a result of insufficient storage.
A storage reservoir is proposed between the pump station at the Rio Grande and thefirst pumpstation within the ID canal network which would have a 640 AF storage capacity, as opposed totheestimated 80AF capacity of their main canal. This would allow for general operationalimprovements within the district, but will also yield anestimated additional 2,000 AF ofsupplyin a drought of record scenario without any additional water rights.

Water Management Strategies - Recommended WMS
United IDalso manages Hidalgo County Irrigation District No. 16, which is upriver from United.With the approval of the Watermaster, United would be able to pump and store any water thatHCID No. 16 is unable to divert as a result of their limited storage and periodic equipmentfailures. HCID No. 16 is estimated to lose 5% of their annual diversions.
A map with the location of the United ID Reservoir is shown in Figure 5-11.

Available Supply
In order to estimate the supplies available with this strategy, the loss estimates from inability todivert were applied to the diversion projections for drought of record conditions. Over theplanning horizon, the United ID losses are estimated at 2,000 AF and the HCID No. 16 losseswere estimated at 900. Taking into consideration that these losses may not be 100% eliminated,and for a conservative estimate, 1,500 AF and 500 AF were estimated for United and HCID 16,respectively for a total increase in supplies of 2,000 AF.
Environmental Issues
Construction of this reservoir would require inundation of 45 acres of land, currently used asfarmland. Temporaryenvironmental impacts may be seen during construction activities, such asincreased air and noise pollution which are typical of any construction project. There would be areduction in water left in the channel of the Rio Grande equivalent to the firm yield of the

project, estimated at 2,000acre-ft./year. There are nodry-year environmental subsistence flowrequirements for the portion of the Rio Grande downstream of United ID's diversion point.Reservoirs constructed entirelyon dry land require no federal 404 permit. Othertypicalenvironmental issues include impacts that may be seen duringconstruction activities, such asincreased air and noise pollution, and land disturbance activities.

Implementation Issues
No additional water rights are required. The District will divert water under its existing rights;Certificate of Adjudication No. A847-001. However, pumping water rights owned byHCID No.16 will require approval bythe watermaster. Construction permitting will berequired.
